48 Hours: Overconfidence?

Did a (in theory) very simplistic workout today and just felt dead. Totally defeated and really felling like I haven't worked as hard as I should. Maybe I got overconfident.

I ran 1 mile to the park then 10 burpees, 5 pull ups, 15 curl ups, then ran to the post office/home (Totaling about 5 miles of running). My legs cried (and rubbed: yay huge legs...), my lungs burned, my throat felt like the Sahara desert, and time seemed to stand still. I did it, but I hated every waking moment of it.

I also made the petrifying discovery that I can not do a single correct pull up (front grip with straight arms to start). I can do underhand pull ups if I start with a very minor bend in my elbow. I was upset by this discovery and got into a funk for the rest of the day.

Two days to race time and here I am with my foot in my mouth. What if I can't finish? What if I hate it? I really want to do well and continue to do these races, but today made me doubt if I can. I went to work and read some more Spartan Up. Let's hope this charade works and I can convince myself that I really can do this.
